Moore Capital Management’s Louis Bacon will donate 90,000 acres of Colorado land to the U.S. Fish and Wildlife Service for a conservation area.

The gift, to be used toward the creation of the Sangre de Cristo Conservation Area, is the “largest single conservation easement” ever given to the service, according to U.S. Interior Secretary Ken Salazar.

“Thanks to Louis Bacon’s deep commitment to conservation, we will now be able to preserve a diverse mosaic of public and private lands, creating a landscape corridor for fish and wildlife unlike any place in America,” Salazar said in a statement.

Bacon owns an estimated 172,000 acres in Colorardo across his Blanca and Trinchera Ranches, the latter purchased from Forbes Magazine founder Malcolm Forbes in 2007 and protected by an easement administered by Colorado Open Lands.

“I have worked on a number of conservation and preservation projects in the United States and overseas, but nothing with the scope and importance of my efforts on Trinchera Ranch, in the breathtaking Sangre de Cristo Mountain Range,” Bacon said in a statement.

The Denver Post says Salazar hopes Bacon’s gift will inspire some of the region’s other large land owners (like CNN founder Ted Turner) to enter similar partnerships with the government. Under such agreements, land remains owned by private individuals but is overseen by U.S. Fish and Wildlife.

Bacon had been in a hard-fought battle to stop solar transmission power lines from crossing his Tranchera Ranch—a battle that ended last fall when the energy company involved, Xcel, decided power generation in the area did not warrant the building of such lines.
